I would like to create a broken line having Y-axis and Y2-axis using Proc sgplot. Could someone please share the sample code. I am attaching the sample layout of the figure to be displayed.

 

Thanks in advance !

You can try the below link for an example , however i am not sure if we plot y2 axis we can break the axis , only with y axis we can get the broken axis, I hope someone will shed light on the possibility.

Hi Jagadish,
Thanks for your reply.
I already tried using ranges to plot the broken axis,but it won't allow to create broken for Y and Y2 axes.

The documentation states:

 

Restrictions This option is valid for linear and time axes only.
Only one axis can be broken. If this option is specified for both axes, then it is honored for the vertical axis and ignored for the horizontal axis.
If this option is specified for both axes in the same direction (X and X2 or Y and Y2), then only the primary axis is broken.
When plots are associated with both the X and X2 axes or with both the Y and Y2 axes, neither axis can be broken.

Yes Richard, this won't work non-linear intervals.Just looking for the alternate solution such scenarios.

What kind of plot, SCATTER, SERIES ? I can't imagine a VBAR with a Y2.

I am looking this current scenario for Series plots.

You could go with the approach outlined here https://blogs.sas.com/content/graphicallyspeaking/2012/05/31/broken-y-axis/ this technique was used when the RANGES= option was not available.

 

See a sample using SERIESPLOT below:

data broken_axis;
  infile cards;
  x = _n_;
  input y y2;
  cards;
100 8
120 15
655 70
688 69
180 08
120 15
655 70
688 73
180 12
;

/*
 * just to get basic graph and GTL
 */
proc sgplot data=broken_axis tmplout="c:\temp\sgplot.sas";
  series x=x y=y;
  series x=x y=y2 / y2axis;
run;

/*--Full Panel Break--*/

      layout lattice / rows=2 columndatarange=union rowweights=(0.35 0.65) rowgutter=2;

          columnaxis / display=(ticks tickvalues) tickvalueattrs=(size=7);
        endcolumnaxes;

          seriesplot x=x y=y / datalabel=y;
          seriesplot x=x y=y2 / yaxis=y2 datalabel=y2;
        endlayout;

          tickvaluelist=(0 10 20)));
          seriesplot x=x y=y / name="y" datalabel=y;
          seriesplot x=x y=y2 / yaxis=y2 name="y2" datalabel=y2;
          DiscreteLegend "y" "y2";
        endlayout;
